Hello meatlover,
After an engine shutdown, Wing Anti-Ice can normally be restored on the side of the failure by opening the pneumatic Crossbleed, but only one air conditioning Pack must be used.
In the event that the engine damage was uncontained, and led to a leak in the Pneumatic system, the Crossbleed must be closed. (If the cockpit rotary selector is in Auto, the Crossbleed should close automatically, if open, but the crew will confirm this by selecting it Shut.)
Hope this helps.
